Abstract
The innervation of the liver and gallbladder
of the lizard Podarcis hispanica has been studied by the
following methods: a) demonstration of cholinesterase
activity; b) FIF method for catecholamines; and c)
immunohistochemistry for VIP.
The hepatic parenchyma of the reptile's liver show
hzpatocytes arranged in regular rows of hepatic cords,
the portal triad being typical of higher vertebrates (birds
and mammals). Nerve fibers are found in the scarce
connective tissue distributed among the hepatocytes.
The innervation is restricted to the big branches of blood
vessels and biliary ducts. It is represented by cholinergic,
noradrenergic and VIPergic fibers.
The gallbladder shows a well developed cholinergic
plexus with pyramidal cells in the interconnection points
of the fiber network. The noradrenergic and VIPergic
plexuses are also more widely distributed in the
gallbladder thali in the liver.
